This article describes the implementation of wireless communication between the control unit and the remote device using IQRF technology. Together with the Node-RED programming tool, it creates a robust, efficient and reliable foundation for the Internet of Things. This paper shows how to quickly design a control system and an IQMESH network. The procedures in Node-RED are presented how to send, receive data, using the MQTT protocol or Http request. The result is a demo application that measures physical quantities of temperature, light intensity and value of a potentiometer. The entire implementation runs on the Raspberry Pi platform and on the IQRF technology, which provides the wireless communication within the IQMESH network.
